How to Fix / Troubleshooting
Safety first: Unplug the freezer before accessing any control boards or wiring.
- Power reset: Unplug the freezer for at least 5 minutes to fully discharge the control board. Plug back in and check if the Er code clears.
- Check for moisture: Inspect the control panel area for signs of condensation or liquid spills that may have entered the electronics. Dry the area thoroughly if needed.
- Inspect wiring harness: Remove the control panel cover and verify that all connectors between the display board and main control board are fully seated and free of corrosion.
- Surge protection: If the error followed a storm or power surge, consider using a dedicated surge protector rated for refrigerators/freezers (if allowed by GE) and have the control board evaluated.
- Replace faulty board: If Er persists and the freezer does not respond to inputs, the user interface or main control board will likely need replacement.
